Control apparatus and method, image capturing apparatus, and image capturing system

A control apparatus that controls image stabilization by actuating at least one of a correction lens included in an imaging optical system and an image sensor that photoelectrically converts light incident through the imaging optical system and outputs an image signal, comprising:

• an operation unit that allows a user to select an arbitrary area in an image output from the image sensor as a reference for the image stabilization;
• and
• one or more processors and/or circuitry which function as:
• an acquisition unit that acquires a representative motion vector based on motion vectors detected in a plurality of areas of images output from the image sensor after the image stabilization is performed;
• and
• a setting unit that changes settings relating to the motion vectors detected in the plurality of areas according to a position of the selected arbitrary area.

An image capturing apparatus comprising:

• a control apparatus that controls image stabilization using a first correction unit that reduces image blur by actuating a correction lens included in an imaging optical system and a second correction unit that reduces image blur by actuating an image sensor that photoelectrically converts light incident via the imaging optical system and outputs an image signal, the apparatus comprising one or more processors and/or circuitry which function as:
• a first acquisition unit that acquires an amount of shake detected by a shake detection unit;
• a determination unit that determines a calculation method for correction amounts that are for controlling the first correction unit and the second correction unit based on the amount of shake and a control method of the first correction unit and the second correction unit;
• a calculation unit that calculates the correction amounts for the first correction unit and the second correction unit based on the amount of shake using the calculation method;
• a second acquisition unit that acquires a representative motion vector based on a motion vector detected from images output from the image sensor;
• and
• a setting unit that sets an acquisition method for acquiring the representative motion vector by the second acquisition unit based on the calculation method;
• and
• the image sensor.
